Northampton
Ironstone, river valley, and the red stain nobody else explains. Window, render, gutter and driveway cleaning across NN1 to NN7.
Two building stocks fail in opposite directions here. Northampton Sand ironstone bleeds a rust-coloured stain that scrubbing and acid both make worse; the modern render estates grow algae instead. Different substrate, different chemistry, different method. Based at Hartwell in NN7.

Where I work — NN1 to NN7
NN1 Abington · Town Centre · The Mounts · Cliftonville · Semilong
NN2 Kingsthorpe · Sunnyside · White Hills · Obelisk Rise · Spring Park · Boughton Green
NN3 Weston Favell · Boothville · Rectory Farm · Blackthorn · Lumbertubs · Round Spinney · Overstone Lodge
NN4 East and West Hunsbury · Wootton · Wootton Fields · Grange Park · Collingtree · Hardingstone · Far Cotton · Delapré
NN5 Duston · New Duston · St James · Dallington · Upton · Harlestone · Hopping Hill
NN6 Brixworth · Spratton · Creaton · Long Buckby · Naseby
NN7 Hackleton · Hartwell · Roade · Grendon · Yardley Hastings
Hartwell is where I am based, so the NN7 villages get the shortest response times on the list.
What I actually do
Glass and frames get pure water through a fed pole, deionised to below 1 ppm dissolved solids and meter-verified before each job. No detergent, so nothing is left behind to attract the next layer of dust, and it dries without spotting because there is nothing in the water to leave a spot. Render, brick and cladding get low-pressure biocidal treatment, never a lance. Hardscapes get hydro-kinetic clearance and a targeted biocide at a pressure chosen for the substrate — sandstone and limestone paving are soft, and the setting you would use on concrete scars them permanently. Gutters are cleared by high-reach vacuum from the ground, with no ladder resting against your ironstone, your render or your fascia.
Finished work on comparable Northampton properties is documented in the case studies, and what changes month to month is written up in cleaning news.
What it costs
Every service has a published rate. You do not need a consultation call to find out what something costs — the figures are on the online price list, and you can put a date in the diary yourself through the appointment calendar. The scope is written down before any work starts. If the property is unusual, or you would rather just talk it through, contact the office.
The other three towns
Eight miles east the ground turns to Oxford Clay and the problem becomes hydrocarbon film from the grid roads — see Milton Keynes. Further east the Great Ouse changes the humidity and the biology with it, covered under Bedford. West of Milton Keynes the geology shifts to limestone and the chemistry inverts completely — Buckingham. All four sit on the region hub, and the practice behind them is described in about Shining Windows.
